PHP+redis database operation method-PHP Tutorial-php.cn

This article mainly introduces the method of operating the PHP redis database. Interested friends can refer to it. I hope it will be helpful to everyone.

The example of this article describes the method of adding voting processing in PHP redis. Share it with everyone for your reference, the details are as follows:

<?php
 header("Content-Type:text/html;charset=utf-8");
 include &#39;lib/mysql.class.php&#39;;
 $mysql_obj = mysql::getConn();
 if(class_exists(&#39;Redis&#39;)){
  //redis 
  $redis = new Redis();
  $redis->pconnect(&#39;127.0.0.1&#39;, 6379);
  if(isset($_SERVER[&#39;HTTP_REFERER&#39;])){
   $url_md5 = md5($_SERVER[&#39;HTTP_REFERER&#39;]);
  }
  $adve_key = &#39;adve&#39;; 
  $adve_key_exists = &#39;adve_exists&#39;;
  if(!$redis->exists($adve_key_exists)){
   $list = $mysql_obj->fetch_array("select * from admin_online_adve");
   if($list){
    foreach ($list as $key => $value) {
     $url_hash = md5($value[&#39;adve_url&#39;]);
     $adve_hash_key = $adve_key.":".$url_hash;
     $id = $value[&#39;id&#39;];
     $redis->set($adve_hash_key,$id);
     $redis->set($adve_key_exists,true);
    }
   }
  }
  $adve_new_key = $adve_key.&#39;:&#39;.$url_md5;
  if($redis->exists($adve_new_key)){
    $adve_plus = $adve_new_key.":plus" ;
    if(!$redis->exists($adve_plus)){
     $redis->set($adve_plus,1); 
    }else{
     $redis->incr($adve_plus);
     $num = $redis->get($adve_plus);
     if($num >100){
      $id = $redis->get($adve_new_key);
      // insert to sql;
      $mysql_obj->query("update admin_online_adve set adve_num=adve_num+$num where id=$id");
      $redis->set($adve_plus,1);
     }
    }
  }
 }
